Error "This is an outdated version": why and what should I do?

The following message could appear if you're working on a song you already worked on in the past.

For instance, when you re-open a completed task or if a task is proposed twice in a mission. 

In these cases, we suggest tapping on "Go back" and select a different track.

If you will tap on "Continue anyway", you will work on an outdated version of the lyrics (most of the time slightly different and without the structure tags).
